Question | Answer |
---|---|
List all the events of the cell cycle. | 1. Interphase 2. Prophase 3. Metaphase 4. Anaphase 5. Telophase 6. Cytokinesis |
List the 3 phases in the Interphase. | 1. G1-cell growth 2. S-DNA replication 3. G2-preparation for mitosis |
What happens in the prophase? | Chromatin condenses into chromosomes and the nuclear membrane breaks down |
What is mitosis? | The division of the nucleus in 4 phases |
What happens in the metaphase? | Chromosomes line up across the center of the cell and each chromosome is connected to a spindle fiber |
What happens in the anaphase? | Sister chromatids separate into individual chromosomes and are pulled apart |
What happens in the telophase? | Chromosomes gather at opposite ends of the cell and 2 new nuclear membranes form around them |
What happens in cytokineses? | The cytoplasm divides |
In what cell does the "draw string effect" forms cleavage furrows (which pinches the cell into two parts) for cytokineses? | Animal cells |
In what cell does a cell plate forms from inside out, and a cell wall begins to appear for cytokineses? | Plants cells |
Each daughter cell has the same number of ___________ as the parent cell? | Chromosomes |
What can happen if the growth of cells is not controlled? | Crowding and tissue damage can happen |
